Equipment for a wide range of petrochemical applications
New projects and revamps have different equipment requirements. Evergreen considers the required separation, available column or vessel space, and operating conditions when developing an internals design.
Equipment selection considers capacity, separation performance, pressure drop, and service-specific requirements such as fouling, corrosion, and polymerisation. Engineering support can include hydraulic design, assessment of existing internals, revamp recommendations, and installation supervision, with the scope agreed to suit project requirements.
Process performance guarantees can be offered for selected applications, subject to agreed feed characteristics, operating conditions, and performance criteria.
Selected petrochemical applications
Olefin Plant — Quench & Primary Fractionator
Cooling and primary separation of steam-cracker effluent. Feedstock, fouling potential and liquid and vapour loads influence the design of the quench and fractionation internals.
- EVERFRAC trays
- Baffle / shower trays
- EVERGREEN column internals
Ethylene / Ethane Splitter
Separation of ethylene from ethane to meet the required product purity. Tray or structured-packing designs must balance separation efficiency and throughput at the specified operating pressure and temperature.
- EVERFRAC trays
- EVERPACK structured packings
- EVERGREEN column internals
Propylene / Propane Splitter
Separation of propylene from propane to meet the required product purity. Separation efficiency, capacity, and pressure drop guide the design of trays, structured packings, and supporting internals.
- EVERFRAC trays
- EVERPACK structured packings
- EVERGREEN column internals
Aromatics Fractionation
Distillation duties for the recovery and purification of benzene, toluene, and xylene streams. Tray and packed-column designs accommodate the required separation and pressure-drop limits.
- EVERFRAC trays
- EVERPACK packings
- EVERGREEN column internals
Terephthalic Acid — Solvent Recovery & Gas Treatment
Solvent recovery and gas-treatment duties associated with terephthalic acid production, including acetic acid recovery. Fluid chemistry and fouling potential influence the design and materials of packings, mist eliminators, and column internals.
- EVERPACK packings
- EVERMESH mist eliminators
- EVERGREEN column internals
Styrene Monomer
Distillation for ethylbenzene recovery and styrene purification. Vacuum operation reduces distillation temperatures; packings and column internals are selected with consideration for pressure drop, liquid residence time, and polymerisation risk.
- EVERPACK structured packings
- EVERGREEN column internals
Methanol Distillation
Purification of crude methanol by removing light ends, water, and heavier impurities. Trays, packings, and column internals are selected to suit the distillation arrangement, operating conditions, and required product purity.
- EVERFRAC trays
- EVERPACK packings
- EVERGREEN column internals
